MACHINE FOR 'H EADING CARTRIDGE-SHELLS.

SPECIFICATION forming part of Letters Patent No. 240,538, dated April26, 1881.

Application filed February 21, 1881. (No model.)

To all whom it may concern: l

Be it known that I, DANIEL E. POWERS, of Vthe city, county, and State ofNew York, have invented new and usefulImprovements in Machines forHeading Shells for Cartridges; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebein ghad to the accompanying drawings, making part of thisspeciication.-

1o Figure 1 represents a plan or top view thereof 5 Fig. 2, a sideelevation; Fig. 3, views of the stop mechanism detached; Fig. 4,detached view of the sliding jaws and divided die for holding the shellswhile being headed; Fig. 5,

view of sliding cam detached; Fig. 6, view of the devices for operatin gthe mandrel-wheel F.

My invention consists in improvements in the construction, combination,and arrangement of mechanism for heading cartridgeshells patented to T.J. Powers, January 18,

Like letters indicate corresponding parts in all the iigures.

v Ain the accompanying drawings represents z 5 the rectangular frame, ofsuitable dimensions,

for receiving and supporting the operating mechanism to head shells forcartridges.

Upon the shaft B is secured the drivingwheel C, through which motion isimparted to the several working parts. To this shaft B is also secured asliding cross-head, D, driven by a crank, E, which head carries a punchfor heading shells in the usual manner.

Upon a shaft, L, directly in line horizontally 3 5 and opposite to theshaft B, is secured a wheel,

f F, upon .the edge of which is arranged, at l suitable distance apart,a series of mandrels,

G, upon which shells are placed while being headed. To this wheel F anintermittent rotatiu g movementis given by means of a ratchetwheel, H,and pawl I, operated by a crank, J,

and connecting-rod K, from the main drivingshaft B. f

Between the shafts B L, and parallel thereto, are arranged two slidingjaws, M, to the inner ends of which are fitted the sectional dies N, forsurrounding and holding the shells While being headed. To these slidingjaws an intermittent back-and-forth movement is given 5o by means of twosliding cams, O, driven longitudi'nally with the frame of the machine byrotating cams P, secured to the main drivingshaft B, as represented inFigs. 2, 5. These sliding cams O move the jaws M forward, so

as to bring the faces of the die secured thereto together and hold themflrmly in such position around the mandrel until the head is formed uponthe shell, and then, by means of the cam P, operating against theopposite bent ends, Q, the dies are separated, and the man- 6o drelholding `the headed shell permitted to move from between them, and thenext succeeding mandrel, with its shell thereon to be headed, to presentitself between the die.

To drive the sliding cams O forward easily, friction-wheels R arepivoted to their lower front corners, against which the revolving camsP, Fig. 5, operate, and friction-wheels S are also provided on the jawsM, carrying the sectional-die N, for the same purpose, Fig. 4. 7o

To stop the wheel F, and mandrels 4Gr thereon, which carry and supportthe shells to be headed in precisely the required position between thedies VN, an automatic sliding stopbolt, T, is secured to the side of theframe A, the end of which bolt takes into notches U, formed in the edgeof the stop-Wheel V, secured to the shaft L, the number of notchestherein corresponding with the number of mandrels Gr on the wheel F. Therequired So movement to lock and unlock this stop-Wheel V is imparted tothe bolt T by means of a friction-Wheel, W, attached to the face of theslide X, which carries the pawl I, operating upon an inclined plane, a,secured to the side of the bolt T, and a spring, b, upon which the boltrests, and which holds it constantly in contact with the face of thenotched stopv wheel, except when forced downward by the friction-wheel Won incline a. When the pawl 9o I has rotated the shaft L, carrying thewheel F thereon, with its mandrels Gr, to the required forward position,with one of the mandrels between the dies to head the shell thereon, asrepresented in Fig. 1, the end of the lock-bolt is forced bythe spring binto one of the notches U, and there it remains until the head is formedon the shell, and during the backward movement of the pawl I to takeinto the next succeeding notch U of the wheel V, the frictionroo holdthe wheel and mandrel firmly, as before,

and so on the operation is repeated in the process of heading shells.

That the shells may always be pushed downupon the mandrels in positionbefore entering between the dies to be headed, a sliding springbolt,di', is arranged upon a stud, f, secured to the upper side of the frameA. (See Fig.- 2.)

This bolt d is driven forward to press the shells down upon the mandrelsby a bar, g, secured to' the' cross-head D, operatingv against' afriction-roller, and the backward movement, to

allow the shells to present themselves beneath its end', is obtained bymeans of a spring, h. Whenl the mandrel-wheel F is at rest, and thecross-head is advancing to head a shell', the ba'r g', secured thereto,moves thev bolt d forward and presses down the shell' uponits mandrel inproper position, and is drawn back by the' spring h, to permit the nextsucceeding. shell' t'o` present itself to be pressed down.

To removethe headed shells from the mandrels, an' automatic talre-oii"7is arranged t'o operate when the mandrels are at rest and While the headis being formed upon a preceding shell'. This take-off consists in aperpendicular slide, k,.secured in proper position beneath the rotatingmandrels and between the inner sides of the frame A, upon the end ofwhich is the usual mechanism for grasping the heads of the shells, asrepresented by dotted lines,l Fig. 2. This slide,l with its talle-o m,is operated by means of a slotted lever, a, hinged to the frame A at p,and a perpendicular sliding rod,`q, also secured to the frame A, to oneend' of which rod is a friction-wheel moving in a cam-groove, t, in aplate secured to the drivin g-sh aft B. Part of this cam-groove tisconcentric with the circumference of the driving-shaft B, to which it issecured, which permits the take-ofi' to remain at rest while a mandrelis being moved forward in position to have the shell thereon headed, andwhile a shell is being headed, and the wheel F,with its mandrels, is atrest, the friction-wheel e moves through the part t of the cam-groove,thereby imparting to the take-oft' m an up-and-down and shell thereon.

movement, to strip the shell from its mandrel before the Wheel Fcommences to move for- Wardh to present the next succeeding shell to thedies.

When the machine is in motion theoperative i places shells successivelyupon the punches G as they are presented by the intermittent movement ofthe mandrel-carryin g wheel F. As the mandrels, with shells thereon, arepresented bei tween the sliding die N, one after another, the jaws M aremoved and firmly held together by means of the cams O embracing amandrel A The cross-head D is then carried forward by the crank E, andthe heady ing-punch r thereon heads a shell.

While a shell is being headed and the mandrel-carrying wheel F is atrest, the take-oft' m,.operated by the cam-groove t and levers q n,removes a headed shell from a mandrel in the usual manner. Theself-actin g stop-bolt T, taking into the notches U, as they arepresented in rotating the shaft L, holds this shaft, with its wheelssecured thereto, iirmly while the operations of headin g and removal ofshells are being executed.

Having thus fully described my' invention, what I claim therein as new,and desire to secure by Letters Patent, is-

1. In a cartridge-heading machine, the combination and arrangement,substantially as herein described, oi' a mandrel-carrying wheel rotatingin a vertical plane, a heading-punch reciprocating in a horizontalplane, anda di'- vided die, the jaws or parts of which reciprocatehorizontally in a plane at right angles to the line of movement of theheading-punch,- the axis of the mandrel-carrying Wheel, theheading-punch, and the crank by which said punch is operated.

2. In a cartridge-heading machine, the cornbi'nation and arrangement,substantially as herein described, of a reciprocating headingpunch, amandrelcarrying wheel, and a notched wheel arranged at the side of saidmandrel-carrying wheel, and on the same shaft therewith, and aspring-stop to engage with the notches of said notched wheel, the wholearranged and adjusted so as to stop the mandrels successively in thelineof the movement of the heading-punch.
